Any option you go with will result in more rasp. You've already changed what prevents rasp, catless headers and catless s-pipe. So if I had to make a decision, only thing I would change are the mufflers for two reasons:
- weight savings (carry the OEM mufflers and you'd be glad you changed them)
- And rasp won't be as pronounced in comparison of changing the x-pipe
Whichever route you go with, the forum would like to see a video
